Install Windows 8

You can now install Windows 8 from the USB drive. If you want to install Windows 8 on a computer that currently has Windows on it, you can insert the USB drive into the computer, browse to the USB drive in Windows Explorer, and launch the setup.exe program on it. This will start the installation process. If you have Windows 7 installed, you can opt to perform an upgrade instead of a clean reinstall that deletes all your files.

install windows 8 from usb

If you have a computer without Windows installed on it, you’ll need to boot the computer from the USB drive. Insert the USB drive into your computer, then restart it. It should automatically boot from the USB drive, starting the Windows 8 installation process.

If this doesn’t happen automatically, you’ll need to change the boot order in your BIOS. Press the key that appears when you turn your computer on (often Delete or F2), locate the Boot Order section in your BIOS, and increase the priority of your USB drive so that the computer will try to boot from the USB drive. Save your settings and exit the BIOS after changing this option. For more detailed instructions on accessing your BIOS and changing the boot order, consult your computer’s manual (or your motherboard’s manual, if you built your own computer). Different computers use different BIOSes that have different interfaces and require different key presses to open.

After going through this process, you’ll be able to install Windows 8 from a USB drive just as you could from a DVD – the USB drive will behave exactly like an installer DVD and offer the usual upgrade and clean install options. You can insert the drive into any computer and use it to install Windows 8. It would be convenient if Microsoft offered better support for this and didn’t require that we download a tool designed for Windows 7 DOWNLOAD The Ultimate Windows 7 Guide DOWNLOAD The Ultimate Windows 7 Guide Read More , but the process is fairly easy.

    Hi. Thanks for this guide, but I always come up with the message "Files copied successfully. However, we were unable to run bootsect to make the USB device bootable" I tried different USB sticks, but the same thing happens. Do you have an idea why?

      Never mind. I tried it with my other laptop and it worked. Thanks for this guide! Installing from a USB device is way faster than installing from a DVD.

    Installing from a bootable DVD or USB to virgin disk. Apart from entering the win8pro key id when requested, is there anything else that will stop doing this clean install of win8Pro Upgrade? IE this is the way to create a clean install of Win8Pro Upgrade.

    I thought the destination partition had to have XP SP3, Vista or W7?

    Also u can do the same from GNU/Linux with dd comand:

    dd if=/path/to/image.iso of=/dev/sdb

    Or better, get rid off that nasty system and move to GNU/Linux

    It would be nice if we can run the Windows 8 OS from the USB itself (may be a USB with a bigger capacity instead of the 4GB) instead of installing it on the PC's hard disk.

        Hopefully that will work. Microsoft officially supports this with the Windows To Go feature, but that's only for Windows 8 Enterprise.
